Abstract
The invention relates to a method for adjusting the flexibility of an assembly fixture of a car body, which is characterized in that according to the given numerical value of the upward bulge of the center of the car body and zero points at both ends, through computer-aided design (CAD) drawing, the circular arc-shaped flexibility curve of the upward bulge of the assembly fixture of the car body is obtained; according to positions which correspond to all supports of the assembly fixture of the car body, heights, i.e. concrete data for adjusting the flexibility of all parts of the assembly fixture of the car body, are measured from the circular arc-shaped flexibility curve. The method for adjusting the flexibility of the assembly fixture of the car body has the positive effects that a function that a circular arc is drawn through three points by a CAD is applied to the adjustment on the flexibility of the assembly fixture of the car body to obtain a circular arc-shaped curve segment. The problem that the adjustment on the flexibility because of the random decreasing numerical value of the assembly fixture of the car body is not accurate is solved, and a graphic data measurement method is realized.
Description
Technical field
The invention belongs to trolley coach manufacturing technology field, relate to the car amount of deflection adjustment that falls of total composition anchor clamps of carbon steel car body, stainless steel car body, aluminium car body.
Background technology
Trolley coach is the prefabricated amount of deflection that raises up in manufacture process, makes vehicle carry operation gravitate recovery level, and prevention is carried operation gravitate car body and stayed.At present, car body is always formed the car amount of deflection that falls of anchor clamps and is adjusted by orthodox practice, with the numerical value mode of arbitrarily successively decreasing of mind-set two ends therefrom amount of deflection is set, because of amount of deflection not on arc curve, so be not the embodiment of true deflection data.
Summary of the invention
The purpose of this invention is to provide a kind of car body and always form anchor clamps amount of deflection method of adjustment, the solution car body is always formed the car amount of deflection that falls of anchor clamps and is adjusted inaccurate problem, and the realization graph data is measured method, reaches by true deflection data adjustment.
For realizing above-mentioned purpose; The present invention provides a kind of car body always to form anchor clamps amount of deflection method of adjustment; It is characterized in that: the numerical value that raises up according to given car body center and two ends zero points; Obtain the total circular arc sag curve that raises up of forming of a car body through the CAD drawing, each supports the position of correspondence always to form anchor clamps according to car body, and on the circular arc sag curve, measuring highly promptly is the concrete data that car body is always formed each position amount of deflection adjustment of anchor clamps.
Good effect of the present invention is: always form the function that the anchor clamps amount of deflection is adjusted Application of CAD three strokes and dots circular arcs at car body, obtain a circle arc curve section.The solution car body is always formed the numerical value amount of deflection of arbitrarily successively decreasing of anchor clamps and is adjusted inaccurate problem, and the realization graph data is measured method.
Description of drawings
Fig. 1 always forms amount of deflection work sheet under the anchor clamps car for car body;
Fig. 2 always forms following 3 the circle arc curve section figure that connect into of car for car body.
The specific embodiment
With reference to Fig. 1, car body always forms 1 need precast the prefabricated amount of deflection line 2 of the car body that raises up in manufacture process, and purpose is that vehicle is carrying gravitate recovery level in service, and prevention is carried operation gravitate car body and stayed.Always the prefabricated amount of deflection line 2 of car body is to form anchor clamps at car body respectively to support under 3 the high low action and form, respectively support 3 height and change be exactly adjustment amount of deflection adjustment car body is always formed anchor clamps, make it to form the prefabricated amount of deflection line 2 of car body.
With reference to Fig. 2; Amount of deflection numerical value that raises up according to the car body center and two ends reset three strokes and dots circular arcs: the body bottom, left of picking up the car end points 4; The maximum of a regulation of the picking up the car numerical value that raises up is car body bottom intermediate point 5; The body bottom, right of picking up the car end points 6 is connected to become a horizontal line with car body bottom, left end points 4 and 6 two of car body bottom, right end points.Known 3 points, the function of Application of CAD three strokes and dots circular arcs obtains a circle arc curve section, and this curved section is the true sag curve 8 of car body.Measure height in the corresponding position of sag curve 8; Centre-height 9 is the total deflection datas of forming 1 center of car body; About height first 10, about height second 11 to be that car body is total form the deflection data that the mind-set both sides are distributed in 1, to be that car body is total form for 1 amount of deflection zero point for car body bottom, left end points 4 and car body bottom, right end points 6.
Through supporting the effect of the sag curve 8 that upwards forms under the car, create the total composition 1 of car body the shape of the prefabricated amount of deflection line 2 of car body.
Claims (1)
1. a car body is always formed anchor clamps amount of deflection method of adjustment; It is characterized in that: the numerical value that raises up according to given car body center and two ends zero points; Obtain the total circular arc sag curve that raises up of forming of a car body through the CAD drawing; Each supports corresponding position always to form anchor clamps according to car body, and on the circular arc sag curve, measuring highly promptly is the concrete data that car body is always formed each position amount of deflection adjustment of anchor clamps.
